Abstract: This study discusses real life problem faced by the conventional treatment plants in order to device a biochemical coagulation process using biological coagulants conducted in laboratory-based experiments. Biochemical coagulation process can be defined as the biochemical destabilization of particles in water to bring about their aggregation during perikinetic and orthokinetic flocculation. Water treatment plants face with the sludge disposal problems, due to chemical coagulants that is iron and aluminum salts. In practice, the sludge from these unit processes are not safely disposed in water or land. Because of chemical sludge contains tiny colloidal solid particles and chemical compounds, there is a need for the present study towards sustainable development. If the sludge is disposed into natural streams and low-lying wetland areas, it may lead to land, air and water pollution. In the present experimental investigation, study of organic coagulants like Nirmali seeds (clearing nut), Jackfruit seed powder, and Conocarpus leaves solution, has been attempted. The biological coagulants are commonly plant based substances that are experimented in the present biochemical coagulation process in jar test apparatus experimental rig for results of turbidity. The comparison of these three natural coagulants are determined by the optimum coagulant dosage requirements for analysis and evaluation of turbidity. It is concluded that present biological coagulants are sustainable coagulation dose requirements to meet global water quality index of excellent standards. The sludge from these biological coagulants may be disposed by the aerobic and anaerobic composting techniques. Otherwise these organic sludges can be dumped in natural streams and lands. Abundantly, the biological coagulants are safe and environment friendly that can be used for water treatment plants.
